Dual-use describes technology that serves legitimate commercial markets and can also be applied to defense, intelligence, or security missions—overlapping worlds with different rules.

How it works

A startup might sell logistics software to retailers while the same routing algorithms help military supply chains. A drone company films farmland for agtech clients and sells reconnaissance platforms to allied governments. Regulators classify many items on dual-use control lists that restrict who can buy them and which countries can receive exports.

In the U.S., ITAR covers defense articles; EAR covers broader commercial items with military potential. Founders need classification determinations, compliance programs, and often separate legal counsel from standard SaaS startups.

Investors split into three camps: commercial-only funds that avoid ITAR overhead, defense-focused VCs that seek government contracts, and generalist funds that diligence export risk before leading.

Why it matters

• Founders: Wrong export or foreign-investor structure can kill deals. Plan classification early; segregate defense revenue if you also want unrestricted commercial growth.
• Investors: CFIUS may review foreign LP or acquirer interest. Dual-use portfolios need compliance budgets and longer sales cycles with government buyers.
• Customers: Enterprise buyers ask whether vendors handle controlled data or components—especially in aerospace, biotech, and AI.

Common mistake

Assuming “we only sell to businesses” avoids regulation. Many dual-use controls follow the technology itself, not your marketing slide. Open-source AI models and commercial satellites still trigger reviews.
